RAISIN-SEPARATING MACHINE.

Applicationifiled September 14, 192 0. Serial No. 410,299.

- To all whom it may concern:

clean the raisins by eliminating any fine substances and third, to provide a machine of this class which is very simple and economical of construction, durable, positive in its I action, sanitary and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter'my invention consists of certain novel features of constructlon, combinatlon and arrangement of parts i and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings'and to the characters of reference thereon which form a part of this applicationin Which:

Figure 1 is a side'elevational view of the machine showing some of 'the partsfragmentarily; Fig. 2 is-a fragmentary front end elevational view thereof; Fig. 3 is a top view of a fragmen'tary'portion thereof; Fig. 4 is a fragmentary portion of the drum and its connection on an enlarged scale and Fig. 5 is a fragmentary end view thereof Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

The end supports 1 and 2, cylindrical member 3, angle members 4:, shafts 5 and 6, rollers 7 and 8, chute 9, chute supports 10 and 11, shaft 12, eccentric 13, feed hopper 14:, receptacles 15 and 16, bearings 17 and base members 18 constitute the principal parts and portions of my raisin separating machine.

The end members 1 and 2 are annular metallic members provided with reduced ofiset portions 1 and 2 so thattheportiQns 1 311C152. form:a},flange so that 'thejrollersi'l and. 8vwill engage-the. portions 1 and 2* and they will beheld in positionbymeansofthe flanged portions. 1 and 2. These members 1 and 2 are held in theirspaced relation by and serve as reinforcements for the cylindri-sv cal meinber13 which is preferably .a sheet by means of anglemembers 1' 'whichare secured to theopposite edges by means ofibolts 'Patenteid 'Mar. 1, 1921.

60, metal member secured together at itsedges v 45. and saidangle bars are secured together by means of bolts 49 shown best in Figs. 1, 4 and 5. This cylindrical sheetv metal mem- Lber is provided with a plurality of rectangular shaped perforations 3 over its complete surface and secured thereto and extending inwardly are a plurality of rods 3 which extend inwardlyas shownbest in Fig. 2 of V the drawings. The rollers .7 and 8 are ;mounted on the-shafts5 and 6 respectively and said shaftsare :journaled in bearings 17- 7 5 1 cured to one of theisupports 17 areiuprights i which are'mounted upon supports "17%: Se-

1 1 upon the upper end of Which-is mounted a feed hopper 14. Mounted in-' the cylindrical member-3 and its one-endextending out-" I wardl therefrom is a chute 9 which is a curvec bottomed preferably metallic chute which is pivotally mounted-on the supports 10 which are i pivotally mounted upon the base-18 and its other end ispivotal'ly con- Q is set on an incline as shown best in Fig. 1

of the drawings so that the raisins will tend to move toward the lower end and pass out into the receptacle 15 and it will also be noted that the inwardly extending rods 3 are gradually set closer together toward the lower end. Mounted under the lower end of the chute 9 is another receptacle 16 to receive the stems.

The operation is as follows: The miscellaneous mass of raisins and stems are fed stems and lighter substances.

through theperforations 3 1 Though particular construction,combination and arrangement of parts and portions I do not wish to be limited to'this particular c0n-.

into the hopper 14 and pass into the cylindrical member 3 which revolves by the contact with. the rollers 7 and 8 and the rods 3 carry the raisins and stems around, the raisins dropping out after a little over a one-fourth revolution while the stems are carried around by reason of their li htness and tenacious quality to approximate y .one half revolution and drop into the'chute 9, raisins and stems beingcarried upwardly in this way several times, unless the stems are caught in the chute and the raisins gradually pass out into the receptacle 15 and stems into the receptacle 16', the chute 9 being reciprocated'to facilitatethe movement of the g I The small particles, dirt and short stem parts pass out I have shown and described a structi'on', combination and arrangement but deslre to include 1n the purvlew of my 1nventionthe constructlon, comblnatlon and arrangement substantially as set forth in the ap ended claims.

Havlng'thu's describedmy invention what I claim as new and desire to secure .by 'Letters Patent is: g

1. A raisin separating machlne, including a cylindrical member positioned on an incline, means for Zrevolving said? cylindrical 1 member, a plurality of-v members extending inwardly fromlthe inner surface of said cylindrical member, means to facilitate the feeding of raisins and stems into said cylindrical member and a chute reciprocably mounted on an incline through said cylin- 'drical member adapted for receiving and conveying stems from the interior ofsaid cylindrical member.

2. 'A machine of the class described, in-' j cluding a cylindrical memberpositioned on an incline provided with a plurality of perforations in its outer surface, means for re- 'volving'said cylindrical member, a; lurality of rodsisecured to and extendin rom the inner surface and, the said cylm rical meminner surface and the said cylindrical member, a chute positioned on anincline in said cylindrical member and means for reciprocatin said chute longitudinally therein.

4:. i raisin separating machine, including a perforate cylindrical member, a plurality of members extending inwardly from the inner surface of said cylindrical member,

means for revolving said cylindricalmem- 7 her and a chute positioned longitudinally through said cylindrical member.

5. A raisin separating machine, including a perforate cylindrical member, a plurality of members extending inwardly from the inner surface of 'said' cylindrical member,

means for revolving said cylindrical member, a chute through said cylindrical member and means for reciprocating said chute.

positioned longitudinally V 6. -A raisin separating machine, including 1 a revoluble perforate cylindrical member, a

plurality of members extending inwardly from the inner surface .of said cylindrical a chute reciprocably .mounted member,

through said cylindrical member adapted to i receive raisinstems and convey them from the IIItGI'IOI Of said cylindrical member.

7. A raisin separatlng'machine, including a revoluble erforate cylindrical member, a

f 'members extending inwardly from the inner surface of said cylindrical plurality 0 member," a chute reciprocably mounted through said cylindrical member adapted to receive r'aisin stems and convey them from the interior of said cylindrical member and means for reciprocating said chute.

In testlmonv whereof, I have hereunto set -my hand at San Diego, California, 'this,8th

day ofseptember, 71920. I
